Modular Interfacial Microswimmers

Ana Mateos-Maroto, Francisco Ortega, Ramón G. Rubio, Carles Calero, and Fernando Martínez-Pedrero

Phys. Rev. Applied 16, 064045 (2021) - Published 17 December, 2021

The transport of microscale matter suspended in a viscous fluid under confined conditions is essential in a wide range of fields and applications, including drug delivery and the study of dynamic self-assembly and constrained dynamics. Designing sophisticated, modular swimmers with different functional units and cooperative dynamic responses enables more complex tasks. In this work, dynamic self-assemblies exploring different transport mechanisms are guided with high maneuverability along a fluid interface. These magnetic micromotors, which do $n o t$ swim via capillary or Marangoni effects, could be used for precise, targeted interfacial transport of drugs under biological conditions.

Superconducting Coupler with Exponentially Large On:Off Ratio

Catherine Leroux, Agustin Di Paolo, and Alexandre Blais

Phys. Rev. Applied 16, 064062 (2021) - Published 27 December, 2021

A significant challenge in the design of large-scale quantum processors is the presence of unwanted qubit-qubit crosstalk, which leads to uncontrollable accumulation of correlated errors. This work introduces a superconducting device that can controllably turn qubit-qubit interactions on and off. The design takes hints from noise-protected bosonic qubits to obtain $e x p o n e n t i a l$ suppression of crosstalk in the off state. These results offer the possibility to keep crosstalk under control in large superconducting processors. Notably, this approach complements the recently introduced protected qubits; an architecture based on them and the proposed coupler would have built-in protection.

Low-Loss Ferrite Circulator as a Tunable Chiral Quantum System

Ying-Ying Wang, Sean van Geldern, Thomas Connolly, Yu-Xin Wang, Alexander Shilcusky, Alexander McDonald, Aashish A. Clerk, and Chen Wang

Phys. Rev. Applied 16, 064066 (2021) - Published 29 December, 2021

Microwave circulators are usually treated as auxiliary, classical components in superconducting quantum computing. This study integrates the cavity-magnon polariton modes of a custom-built circulator with superconducting microwave cavities to implement a tunable nonreciprocal interaction. The apparatus is well described by a non-Hermitian Hamiltonian, yielding a theoretical framework to model other nonreciprocally coupled circuit elements on the same platform in the future. The experiment also showcases an experimental probe of the left and right eigenvectors associated with the non-Hermitian Hamiltonian.

LETTER

Superconducting Terahertz Sources with 12% Power Efficiency

R. Cattaneo, E.A. Borodianskyi, A.A. Kalenyuk, and V.M. Krasnov

Phys. Rev. Applied 16, L061001 (2021) - Published 10 December, 2021

Low power efficiency is one of the main problems concerning the photon sources that would fill the so-called “terahertz gap”. This Letter presents prototypes of devices based on whisker crystals of the high-temperature superconductor Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ , with a radiation power efficiency of 12% at frequencies near 4 THz. This efficiency is more than an order of magnitude larger than those in earlier studies and approaches the theoretical limit of 50%, paving a way toward creation of sources that are tunable, monochromatic, continuous-wave, compact, and most importantly power-efficient.

Phys. Rev. Applied 16, 064063 (2021) - Published 28 December, 2021

Thermophotovoltaic (TPV) systems hold promise for recycling heat into electricity, but a key challenge is to lower the operating temperature to the range of industrial waste heat, at high efficiency. The authors offer a thermodynamic analysis of the open-circuit voltage of TPV systems operating in the far and near fields, and compare to solar PVs. An analytic model shows that although nonradiative losses increase in the near field, luminescence efficiency improves significantly in this range. This work suggests that an ultrathin near-field TPV system can exhibit ultrahigh open circuit voltage and high efficiency, for emitter temperatures much lower than its far-field counterpart.
